forms over data video series

Let AB and CD be two intersecting lines intersecting at O, forming four angles. XOX and YOY bisect the four angles. Let P be a point in the plane such that if PM ^ AB and PN ^ CD, then PM=..

">Hydrocarbons and their major sub groups form a homologous series of organic compounds. As an illustrative example, the simplest of all hydrocarbons is methane whose molecular formula is CH 4 . This molecule consists of a single carbon atom linked to four hydrogen atoms by sing..

The table shows the monthly details of the number of videos rented from a store. Which of the given graphs is the most appropriate to show the data? Month Number of videos rented October 127 November 129 December 138 => circle graph or stem-and-leaf plot or line graph ..

Alkanes, alkenes, alkynes, alcohols, aldehydes, carboxylic acids etc. form separate homologous series..

A series of the form a + (a + d)r + (a + 2d)r 2 + ... is called an Arithmetic-Geometric series. In the series if we put d = 0 we get GP and if we put r = 1, we get an A..

1) Reactive metals are placed on top (e.g., Li) and they have a great tendency to get oxidized. Non-reactive metals like Ag and Au. 2) Any metal above hydrogen can displace it from dilute acids. Example: Any metal which is above another can displace that from its salt solutions Example: If two meta..

Different metals get ionised at different rates. For e.g., metals like sodium when exposed to air combine almost instantly with the oxygen present therein (sodium atom gives up an electron almost as soon as it is in contact with oxygen). On the other hand, metals like gold if exposed to air even fo..

The higher the metal in the series, the more reactive it is i.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more suscepti..

1) Higher the SRP, greater is the tendency to accept e - , higher is the tendency to get reduced and greater is the oxidizing power. Fluorine system (F 2 /F) - has the highest SRP and hence it possesses highest oxidising power and this increases down the group. 2) Lower the SRP, lesser is the tende..

Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease with which an element loses its electrons and acquires a posit..
